Tutorial: Kondo RCB-3HV Upgrade – Interpolation Functionality


In our earlier RCB-3HV Upgrade announcement post, we mentioned the added ability to automatically create a number of new position objects (POS) between two existing objects. It turns out that this functionality is quite useful in creating new motions. For example, you might capture the start and end poses for a particular motion, then use the new function to create the necessary intermediate positions. Of course, they may not be exactly what you need, and may require some minor servo and speed adjustments, but it gets you 90% of the way very quickly.

We put together the quick tutorial below showing how the new H2H3 used with an upgraded RCB-3HV controller works.

To show how the function linearly interpolates servo positions for the new intermediate POS objects, we used a very simple motion sequence consisting of two consecutive POS objects, and only activated the servo bars for two channels. Keep in mind that in actual practice, this function will interpolate the positions of all active servos.

  1. Hi Scotty,

    I use Flash for screenshot based tutorials since it’s better than video, and easier to edit for applications like that. Video definitely has it’s uses, but a video of a screen process like this one would probably end up looking pretty bad and unreadable on YouTube the way that their conversion process works.

  2. Limor,

    I’m glad you like it. I plan to add a lot more tutorials in the future.

    The software app I use to create them is Wink (link to debugmode.com). It’s simple, easy to use, yet has enough features to get the job done, and it’s free… !8-D
